Centrifuge similarity simulation test box - HLXS,The commonly used equipment in geotechnical engineering and geomechanics experiments is mainly used to measure the shear strength parameters of soil, sand or other granular materials (such as internal friction angle φ and cohesion c). Apply shear force horizontally to cause the soil sample to fail on the predetermined shear plane.

Applicable to

• Soil stability analysis: such as the design of slopes and foundations.

• Research on material properties: Compare the shear performance of different soil types (clay, sand) or improved soils (such as those with added fibers and binders).

• Teaching demonstration: Visually demonstrate the process of shear failure.

1. Axial loading technical parameters.

Axial loading drive: servo motor controls loading, with a noise level of 50 decibels during the test process;

Axial loading: 5Hz/10kN;

The pressure chamber base with a twelve channel ring is fixed on the host, and the axial dynamic force is applied from below the pressure chamber base. The upper part of the pressure chamber is open;

Built in balance cylinder, used to compensate for the volume change of liquid in the pressure chamber caused by the entry and exit of the loading rod, and can maintain stable confining pressure during dynamic cyclic loading; Displacement stroke: 0-100mm, JINGDU0.5um, measured by a grating ruler displacement sensor;

The built-in force sensor interface is used for force feedback, with static control of JINGDU 0.02% and dynamic control of JINGDU 0.1%. The dynamic axial stress is applied from below the pressure chamber, and above the pressure chamber is an open operating space without the need to load a crossbeam for easy sample installation. The axial stress testing accuracy is 0.1kPa; Axial loading force: dynamic and static axial force of 10kN;
